Title: Improvements in or relating to motor-generator sets
Inventor: MANDL ARTHUR
IPC: H02P11/04
Filed: 1953-05-27
Abstract: 745,396. Automatic voltage control systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 7, 1954 [May 27, 1953), No. 14525/53. Class 38 (4). The output voltage of the generator of a D.C. motor-generator set supplied from a fluctuating D.C. traction supply is maintained constant by a vibrating contact regulator which can either shunt the field of the generator (when the set is running fast from a high input voltage and on low load) or the field of the motor (when the opposite conditions prevail). The motor field m and the generator field g are connected in series across the output of the generator G. A vibrating contact C responsive to the generator output voltage operates under conditions of light load and high input voltage to intermittently connect shunt rg across the generator field g, thereby reducing the generator field and increasing the motor field. Under conditions of heavy load and low input voltage, contact C intermittently connects shunt rm across the motor field m. The motor is stated to include an auxiliary series field, and the generator has an unregulated shunt field g<SP>1</SP>. The proportioning of the various field windings is discussed.

Title: An improvement in or relating to hydraulic lift mechanism for agricultural tractor-implement combinations
Inventor: HULL CHARLES HARTLEY
IPC: A01B63/10
Filed: 1953-05-26
Abstract: 738,881. Agricultural implements. BROWN TRACTORS (ENGINEERING), Ltd., D. May 26, 1954 [May 26, 1953], No. 14552/53. Class 6 (1). A tractor-implement linkage comprising two laterally-spaced lower links b, f and a central upper link r is characterized in that each of the lower links is operable by a separate hydraulic piston and cylinder and the upper link r incorporates a further hydraulic cylinder n and piston q operable to lengthen or shorten the link r. As shown, hydraulic fluid is fed from a supply conduit d to the bottom of a cylinder a by means of a valve c. The upper end of cylinder a is connected to the lower end of a cylinder e by a conduit g which is fed by hydraulic fluid through a valve h. When the interconnected spaces above piston i and below piston are filled with liquid, the admission of fluid below piston i results in both the lower links being raised simultaneously. Admission of fluid through valve h will result in raising the piston j relative to the piston i, thus adjusting the transverse level of an implement. Both ends of the cylinder n are interconnected and joined to the conduit d through a valve p. The piston q has a difference in area between its two faces due to the attachment to one face of the piston rod. Thus admission of fluid through valve p will cause lengthening of the effective length of the upper link r. The cylinder n may be connected to the supply conduit d by means of two separate conduits and valves.

Patent GB-1008314-A (GB)
Title: Production of cycloalkanones
IPC: C07C29/52
Filed: 1962-04-18
Abstract: Cycloalkanones are made from their corresponding cycloalkanes by liquid phase oxidation with gaseous molecular oxygen in the presence of an oxygen-containing boron compound, which is capable of reacting with the cyclo-alkanols formed under the prevailing reaction conditions to form esters, followed by the dehydrogenation of the cycloalkanols formed.  Preferably, the oxidation reaction is carried out at 75-300 DEG  C. using air and a catalyst, such as cobalt naphthenate or manganese naphthenate, water formed during the reaction being removed by distillation as a cycloalkane-water azeotrope.  Preferably, at the completion of the oxidation reaction, excess cycloalkane is removed, e.g. by distillation either before or after the cycloalkanol is liberated by hydrolysis, which is preferred, alcoholysis or transesterification. The cycloalkanol thus obtained, and from which boron compound has been removed, is dehydrogenated preferably at a temperature in the range of 325-425 DEG  C. and at a pressure between 2-45 p.s.i.a. in the presence of a catalyst of zinc oxide, to form the corresponding cycloalkanone. Desirably the cyclo-alkanol fraction is treated with a dilute aqueous alkaline solution, e.g. of caustic soda, before dehydrogenation is effected.  Boron compounds specified are boric acid, metaboric acid, tetraboric acid, boron oxide, methyl borate, ethyl borate, ethyl metaborate, ethyl triborate and ethyl boric acid.  The quantity of boron compound used is desirably at least sufficient to provide the equivalent of 1 mol. of boric acid (as H3BO3) per mol. of cycloalkanol formed in the oxidation reaction.  Five examples are given, illustrating the increased yield of cyclohexanone and methylcyclohexanone obtained when using different quantities of boric acid and boron oxide as compared with a comparative example in which no boron compound is present.  Specifications 996,791 and 996,792 are referred to.
